For my PCE I worked as a behavioral therapist for 3.5 years and a mental health therapist for 3 years (I also have a Masters in Counseling). Last month I finished a CNA class and plan on getting a part time job as a CNA to expand my PCE. The CNA class I took was through a local nursing home training center. In minnesota where I live it's a 70 hour course.
In regards to prerequisites I took intro chem 1&2, o chem, biochem, microbiology, a&p 1&2, and genetics. I took these courses over the last 3 years or so. I could have finished these classes in less time but I work full time and have 2 kids so I only took 2-3 class a semester and took 1 semester off when we were moving.
I would look at the schools that you would like to apply to and see what their requirements are and start making a plan based on those requirements.

Thank you for your kind words and advice. I am definitely going to get some more prerequisites done so I can apply to a few more schools. Unfortunately I cant apply too far from home since I'm trying to avoid uprooting my kids and want to stay within easy driving distance so my husband and kids can easily come visit if they dont move with me.

So this is my 3rd year applying. The first year I only applied to 2 schools to get a feel for the process, interviewed at 1, and was rejected. The second year I applied to 7 schools, interviewed at 3, and was waitlisted at 2. This year I applied to 5, interviewed at 3, and was waitlisted at 3.
I guess I'm just incredibly frustrated. I've done mock interviews and the interviewers say I do great. I've felt like the actual interviews go well and I get waitlisted, which I know is still a huge accomplishment but I just wish I could get that one acceptance. plus next year some of my prerequisites are hitting the 5 year expiration mark for one of the programs I have been waitlisted at the last 2 years, so this makes me wonder if I should start retaking these classes to qualify for this program that I have gotten close to getting into on multiple occasions.
Stats: I have a 3.4 cumulative undergrad GPA, 3.25 science GPA, and 3.9 graduate GPA. Approximately 4000 hours as a mental health therapist, 5000 hours as a behavioral therapist with children with autism spectrum disorders, and 350 hours as a job coach for individuals with disabilities.
To prep for the next application cycle I am taking a few more upper level science courses to open up more schools I can apply and also going to get my CNA so I am able to get some different health care experience in addition to continuing to work as a mental health therapist.
Is there any other advice anyone can give me to make me a more competitive applicant? (Raising GPA isn't much of an option since I have approximately 160 undergraduate credit hours). I've tried contacting all of the schools I have applied to and they all state that they do not provide individual feedback.
Thank you for your time reading this leangthy post.

I emailed them asking what this status meant and this is the response I received.
"Thank you for your email and interest in Rosalind Franklin University.The admissions committee has conducted an initial review of your application, which displays evidence of your academic potential.Your application will be reviewed further, there is nothing additional that you need to submit to strengthen your application, but if there are any changes in your health care hours or completed coursework, you may log in to CASPA to update your application accordingly. Please allow another 4-6 weeks for the holistic review process to be completed. Your application can be placed on the waiting list from the continued consideration status. If that is the case this will mean that you are admissible into the program and if a seat becomes available you will be pulled from the wait list to fill that seat. "

For advice I would say just try to be yourself and maybe practice answering some typical mmi style questions to practice what talking for approximately 5 minutes feels like. Also for the last interview thing I'm not sure about that because it also said the same thing in my interview reminder for the October 12th interview. At the time of the interview they had said there was still spots open. I do know that myself and 1 other person from that interview date were placed on the waitlist. Hope this is at least a little helpful ?
